bind failed in LDAP authentication phase

[Rafael Roldán]

Hy all,

I am still doing tests with the rlm_ldap module and I have encountered with
the following problem:
In the authenticate phase the user replica try to bind to the LDAP server.
But this attempts fails. However, in the access control section of the LDAP
server, it has permission...

I don´t know what I am doing wrong

I have configured my LDAP server with the following control access. In the
slapd.conf:

access to *
        by self write
        by dn="cn=billing,ou=admins,ou=radius,dc=mydomain,dc=com" write
        by dn="cn=freeradius,ou=admins,ou=radius,dc=mydomain,dc=com" read
        by anonymous auth
        by * none
----------------------------------------
My users file:

DEFAULT NAS-Port == 58, User-Profile :=
"uid=isdn,ou=profiles,ou=radius,dc=mydomain,dc=com"

DEFAULT Auth-Type := Reject
        Reply-Message = "Llamse a servicio tecnico"
